Resumo: | The addition of citric acid to the substrate may potentiate the availability of phosphorus in coffee seedlings. The growth and accumulation of nutrients by Coffea arabica seedlings on substrate treated with citric acid with different doses of P2O5 was evaluated. The experimental delineation was arranged in randomized block design (DBC), with five repetitions in 3 x 4 factorial scheme, consisting of three genotypes (Catuaí Vermelho IAC 99, Mundo Novo IAC 379-19 and Oeiras MG 6851) submitted to four doses of P: zero, 450, 900 and 1,800 mg dm-3 P2O5). Single superphosphate was used as the source of P2O5. The seedlings, when presenting the first cotyledonous leaves, was applied anhydrous citric acid at dose of 0.425 mg dm-3 per seedling. After 180 days, the variables of growth, accumulation of dry matter and nutrients by coffee plants were evaluated. The doses of P2O5 in substrate treated with citric acid, positively influenced the growth of coffee seedlings. The highes accumulation of biomass and nutrients were mostly in the dose of 900 g m-3 P2O5. No variation was observed among genotypes in relation to foliar nutritional analysis. The increase of phosphorus doses in substrate treated with citric acid increases the concentrations of Ca, Mg, Fe and Zn in the foliar tissues of coffee plants. |

O objetivo deste estudo foi avaliar o crescimento e acúmulo de nutrientes por mudas de Coffea arabica, genótipos Catuaí Vermelho IAC 99, Mundo Novo IAC 379-19 e Oeiras MG 6851 em substrato com ácido cítrico e doses de P. O delineamento experimental adotado foi em DBC, esquema fatorial 3 x 4 (três genótipos submetidos a quatro doses de P: zero, 450, 900 e 1.800 mg dm-3 de P2O5), com cinco repetições. Utilizou-se o superfosfato simples como fonte de P2O5. Quando as plântulas apresentaram as primeiras folhas cotiledonares foi realizada aplicação de ácido cítrico anidro na dose de 0,425 mg dm-3 por plântula. Após 180 dias foram avaliadas as variáveis de crescimento, acúmulo de matéria seca e nutrientes pelas plantas de café. As doses de P2O5, em substrato tratado com ácido cítrico, influenciaram positivamente o crescimento de mudas de café. Não foi observada variação entre os genótipos com relação à análise nutricional foliar. O incremento de doses de fósforo em substrato tratado com ácido cítrico aumenta as concentrações de Ca, Mg, Fe e Zn nos tecidos foliares de plantas de café.Universidade Federal Rural da Amazônia/UFRA2019-03-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/2768Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 62 (2019): RCARevista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 62 (2019): RCA2177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
